IMPROVEMENT IN PUMPS.

TO ALL WHOM IT MAY CONCERN:

Be it known that I, HENRY GETTY, of the city of Brooklyn, county of Kings, and State of New York, have invented, made, and applied to use a new and improved Double-Acting Lift and Force-Pump for Shallow and Deep Wells, Fire Engines, Sto., Sto.; and I do declare the following to be a full, clear, and lcorrect description of the same, reference being had to the accompanying drawings, making a part of this specification, and to the letters of reference marked thereon, in which-- Figure 1 is a perspective view of my new double-acting lift and force-pump with escape-valve as used for deep wells.

Figure 2, alongitudinal sect-ion of tho same, showing the pump cut in half, with the up stroke in red lines.

Figure 3, a view of` the hollow ram or plunger detached from the pump, with its piston, valve, and yoke.

In the drawings like parts of the invention are indicated by similar letters of reference.

The nature of my invention consists in dividing the body of the pump into two cylindrical chambers separated by a partition forming a stuiing-box, the upper chamber having a hollow ram or plunger working inzit, which is provided with a piston and valve at its lower end working in-thelower chamber, which latter is provided with apertures for the admissiomot` air at its upper end, when used for ordinary wells, that the piston may move `freely either up or down, or with a valve or valves when used for deep wells, so as to act as a vacuumchamber to aid in lifting the plunger and pump-rod on Iits upward motion, the arrangement of the whole being such that it shall operate as a direct-acting lift and force-pump with only two valves, and with a straight passage for the water through it.

To enable those skilled in the arts to make and use my invention, I will now proceed to describe the construction aud operation of the same.

C, g. 2, shows the base ofthe pump. It is made of cast iron or other suitable material, and is screwed or attached to the lower chamber B ofthe pump. On the upper side of C, I form a seat for the suction-valve a", with a cage, if a ball-valve is used, to prevent the ball rising too far. Its lower part is screwed or otherwise formed for the attachment of the suction pipe. The lower chamber B of the pump is also formed of cast-or wrought iron or other Vsuitable material, and is bored or otherwise made perfectly true inside for the reception of the piston F, which works in it. It is screwed or otherwise formed at its lower part to be attached to the base C, and its upper part is provided with means for attaching it` to the partition D. Partition D isr formed with a screw at both ends, and provided with an annular shoulder for the chambers A and B to screw up to, or it may be made with a screw its whole length, and let the two chambers abut against each other, so as to form a tight joint. Its centre is bored out for the reception of the hollow ram or plunger P, and has a stuilng-box formed on one sidefof it for the purpose of keeping the hollow ram or plunger water-tight. The hollow ram or plunger P may be made of brass or other suitable material, and turned true on the outside to fit the hole in partition D.

At` its lower end I form the piston F, which is firmly attached to it, and inside said piston, opening upward into the hollow ram or-plunger, I insert the valve a. AIts upper end is left open, and is screwed or otherwise suitably formed for the reception of the yoke Y, to which yoke the pump-rod R is firmly attached in any suitable manner. The upper'chamber of the pump A does not. need boring out inside, as the hollow ram or plunger does not touch its sides. When used for an ordinary pump, I provide it witha stuHing-box, I, for the rod R to workthrough, and a spout. When used for deep wells its upper end is suitably formed for the .reception of the ascending pipe, through which pipe rod R may work, or I provide it with a. branch pipe and air-chamber, and let the pump R workvthrough the top of it, and ailix the air-chamber and ascending pipe at its side.

The parts being all put together, as in g. 2, with the escape-valve S omitted, the operation of the pump is as follows, when used for ordinary purposes: When the pump-rod R is raised it carries the hollow ram or Aplunger P and piston F up with it. Valve ce closes, and the suction-valve a opens, and chamber B is filled with water. The air'between the hollow ram and chamber B is at the same time expelled by the rising ofthe piston through the holes o o in the upper part of chamber B. When the pump-rod R descends, the valvea" closes, and the piston F, having double the areaof the hollow ram or plunger P, forces the water in chamber B through the valve a and hollow ram or plunger P into chamber A.V The hollow ram or plunger Pis now filled with water. ABy the descent of the piston F there would be a vacuum formed between the hollow ram or plunger P and chamber B, but this is prevented by air entering t'reely'through the hole or holes a o in upper` part of chamber B. When the rod R again ascends, valve a4 closes, and the hollow ram o r plunger P, heilig now filledwith water, acts as asolid ram, and a quantity of air or water' of the" sanneY aree.r as it is forcedout of chamber'A 'through discharge nozzle E. On the rofl R again descending, the pistool?` forces the water which has entered the chamber B through the hollow rain or plunger P, and it is discharged at the nozele of the puinptiE. Thus the hollow ram or plunger P becomes alternately a solid ram to forcethe Ywater out of chamber A, 'and a. hollow tube for the conveyance of the water forced out of chamber B by the piston F into chamber A. When used for deep wells I stop the hole or holes o o, and let the down stroke of the lpump-rod R by means of piston F create. a vacuum in the space between the hollow ram or plunger'P and chamber B, which on the upward stroke gives an additional power to it and helpstto raise the Weight ofv therods and water.' I insert when thus used a small valve or valves, S, in the lhole or holes o o in the upper -partvof charnber B, which valve -or valves open outward from said chamber B, andare held firmly down against the pressure of the atmosphere from the inside of said chamber B by aspring onweighted lever, -for should any water escape past the-piston F into the annular space, the pump would stop working. By the'use of the escape-valve S any water which escaped past the 'piston will be expelled through the escape-valve.

Having thus fully explained my invention, and described the operation of -the same, what I claim as my invention, and desire to secure by Letters Patent, is-

The hollow plunger P, acting in its up stroke as a solid ram, and in its down stroke as a water passage, provided with a valve' and-piston-packin'g at its lowcr end, and working in the cylindrical chambers A B, provided with an annular'collar at the point of their junction, forming a smiling-box, throng-h which said plunger Precip- ,rocates all arranged and operating substantially as set forth.
